The first time I looked into mystery shopping, years ago, there were a lot of places that wanted you to pay for directories of shopping companies. This is such a scam. Please know that you can find this information on just about any mystery shopping website. Never pay to do this!
I wish I would have known this before I paid a mystery shopping company $100 to use their proprietary software. At the time I thought “I’ll make it back quickly!” except that for weeks I checked back and found zero jobs I was eligible for. Thanks for the tip!
